This mailer contains several different transports for your emails. To be sendable, the emails have to implement SendableEmail, which is the case for emails created with lettre_email.

The following transports are available:

• The SmtpTransport uses the SMTP protocol to send the message over the network. It is the preferred way of sending emails.
• The SendmailTransport uses the sendmail command to send messages. It is an alternative to the SMTP transport.
• The FileTransport creates a file containing the email content to be sent. It can be used for debugging or if you want to keep all sent emails.
• The StubTransport is useful for debugging, and only prints the content of the email in the logs.
